smugmug_status

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full disclosure burden. It does add useful scope detail (it inspects account, credits, and SmugMug connection), but it does not say the call is read-only, whether it consumes credits, what happens on a failed connection, or what the response contains — meaningful gaps for a status tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence, front-loaded with the action verb, with the three checked items listed compactly. It is efficient and easy to scan; the colon-list phrasing is slightly awkward but not wasteful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter tool this is nearly sufficient, but there is no output schema, so the description should ideally indicate what the readiness result looks like (per-check pass/fail, remediation hints for missing credits or an unconnected SmugMug). As written, an agent knows what is checked but not what it will receive back.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so the baseline is 4. The description correctly implies no inputs are required, and there is nothing in the schema for it to contradict or need to compensate for.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a specific verb ('Check') and enumerates exactly what is verified: account, credits, and SmugMug connection. This clearly reads as a readiness/diagnostic check, which is distinguishable from the sibling browser-automation tools (open, click, type, read, close), though it never names them explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Use is only implied by 'ready' — an agent can infer this is a precondition check to run before real work, but the description never states when to call it, whether it must precede other smugmug_* tools, or when it is unnecessary. No alternatives are named.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
